Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a temperature sensor calibration mechanism. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. There are many types of temperature sensors, which can be divided into two types according to the measurement method. One is a contact temperature sensor, which refers to a temperature sensor that is in direct contact with the object being measured, also known as a thermometer. The other is a non-contact temperature sensor, whose sensitive element does not contact the object being measured, also known as a non-contact temperature measuring instrument. This instrument can be used to measure the surface temperature of moving objects, small targets, and objects with small heat capacity or rapidly changing temperature. It can also be used to measure the temperature distribution of a temperature field. There is a certain deviation in the use of the temperature sensor, so the temperature sensor needs to be calibrated.

[0003] Most temperature sensors on the market are not calibrated rigorously and are not automatically calibrated, which results in large differences in the data values ​​of the temperature sensors when they are used for measurement. This reduces the accuracy of the temperature sensor measurement process and the calibration effect, thus requiring improvement in the temperature sensor calibration mechanism. Utility Model Content

[0010] Furthermore, a through hole is provided inside the cleaning box, and both the thermometer to be measured and the thermometer pass through the cleaning box through the through hole.

[0011] Furthermore, the cleaning brush is composed of cotton strips and is U-shaped.

[0012] Among them, the number of slivers is several.

[0013] It should be noted that the cotton strips in the cleaning box can be replaced by viscose.
